* Added the new $an->_get_hash_reference() method that takes a key in the format "foo::bar" and returns the contents of $an->data->{foo}{bar}.
* Added the new Words->clean_spaces() method that removes leading and trailing spaces from a string, and condenses multiple spaces into single ones to simplify string parsing.

* Created tests for most existing module methods now.
* Updated Storage->search_directories to handle merging @INC and $ENV{'PATH'} when called with an invalid directories parameter, and exploited this behaviour to initially set the directory search list. This also deprecated the Tools->_add_environment_path_to_search_directories() method.
* Added Storage->read_config based on the old v2 'Storage->read_conf()'. Also ported over the old Tools->_add_hash_reference() and Tools->_make_hash_reference() methods to assist with this method's operation.
* Created Words->key() that returns the raw string for a given language and key.
